Holding time for a ref number of complaint

Upset is really an understatement <br> <br> Cell C fails at informing one, of the most important information. This before and after you found yourself in a painful and long 24 mouth payment agreement for bad service... unhelpful agents and need I go into the LONG waiting call time you have to go through just to be unhelped and kept on hold during this pain. <br> <br> May I keep this short. May Cell C take time to listen this call reference: #***, between agent I who kept me on hold just to give/text me the *** and the matter which kept me on the phone for 20 minute...<br> <br> After this, will someone get back to me with a simply solution of terminating and ending thing this agreement which I found myself in. From my side, I delivered to the agreement and my 24 for months ended on 01/03/2015... yet I'm being billed for the 25th months... I thank the call and offer I was informed of in December for an early upgrade which I decilined but never was I informed of a 30 day which I need to send before of end of contract... Nor was I given a call..email or sms to inform me of contract expiration on 01/03/2015. But I did get the invoice today informing me of the invoice for month 25..
